For tablets? I doubt it.
The most popular non-Apple tablet, the Kindle Fire, isn't available elsewhere.

The Nexus 7 is also not available everywhere, whereas the iPad is.
Of note: 62% of Apple revenue comes from International sales so it's not as if their international popularity is all that much lower than in the US.http://techcrunch.com/2012/07/24/apple-q3-2012/
